Backflushing maintenance-free detachable modular ecological dam for two-way purification treatment of water body

Abstract

The invention relates to the technical field of ecology, in particular to a backflushing maintenance-free detachable modular ecological dam for two-way purification treatment of a water body. The backflushing maintenance-free detachable modular ecological dam comprises an ecological dam body and is characterized in that the ecological dam body is formed by splicing a plurality of treatment modules, and each treatment module sequentially comprises a first medium-efficiency filtration treatment module, a first high-efficiency filtration treatment module, a high-efficiency reoxygenation biodegradation treatment module, a second high-efficiency filtration treatment module and a second medium-efficiency filtration treatment module from front to back. Compared with the prior art, the backflushing maintenance-free detachable modular ecological dam has the following beneficial effects: 1, the ecological dam body is formed by splicing the single treating modules, is easy and convenient to dismount and mount, and meets the passage requirements of flood prevention, flood discharge and emergency rescue working ships; 2, a supporting structure ensures the use stability of the ecological dam andprolongs the service life of the ecological dam; 3, two-way water flow treatment of a tidal riverway is met, the backflushing purification design is required, the maintenance frequency is reduced, and the maintenance-free effect is basically realized; and 4, a multi-stage physical and biological treatment module is arranged, so that the purification efficiency is improved.

Description

technical field [0001] The invention relates to the field of ecological technology, in particular to a maintenance-free detachable modular ecological dam for two-way purification treatment of water body and recoil. Background technique [0002] In recent years, affected by modern agriculture, urban development and human activities, a large amount of agricultural non-point source pollution and some factory sewage and domestic sewage have been directly discharged into water bodies without treatment, and finally flowed into rivers; domestic waste and construction waste are directly discarded into In the river channel, the water flow in the river channel is seriously polluted, the water quality deteriorates, and it has a great impact on the ecological environment on which human beings depend. [0003] Therefore, a detachable modular ecological dam with recoil and maintenance-free two-way purification treatment of water body is designed, which can purify the water quality of the ...
